Description
1. [10 pts] Go to one of the desktop machines in the CSEL and invoke the Unix
drawing tool xfig. Play with the four spline- and curve-drawing tools, whose
icons look like figure eights and S curves. Try some of the examples from the sheet
that I handed out in class on March 8th.
Using your knowledge about different kinds of splines, do some experiments and
form some conjectures about which ones xfig uses for the tool whose icon looks like
a smooth figure eight and the one that looks like a figure eight with superimposed
dots. With each answer, turn in a few sentences that describe your rationale for
making that diagnosis.
Suggestions:
• try some colinear points
• use the ‘move-point’ tool (next to the ‘move’ tool)
• look at the slope of the spline at the endpoint
